Abstract (en)
[origin: WO2020088462A1] The present disclosure provides a method (700) for generating a Demodulation Reference Signal, DM-RS, sequence for channel estimation and demodulation in New Radio network when transform pre-coding is enabled in transmissions. The method includes: determining (701) a cyclic shift value for cyclic shift of a base sequence; and generating (702) a corresponding Demodulation Reference Signal, DM-RS, sequence based on the cyclic shift value. The present disclosure also provides a DM-RS sequence generation apparatus, a UE and a base station.
